ARC Research Hub for Offshore Floating Facilities. This research hub aims to address the critical engineering challenges associated with Australia’s next generation of offshore oil and gas projects. These projects, in remote deep-water locations, will require innovative floating facilities. Using world-leading expertise in metocean, hydrodynamic, geotechnical and reliability engineering, the hub aims to develop the new technologies and analysis methods that are required to make projects safe, efficient and cost-effective. This research will include wave and current forecasting, vessel motion and offloading analysis, riser and mooring longevity and novel anchoring and subsea foundations. This is expected to lead to safer, more economical projects and should develop Western Australia’s role as an oil and gas centre of excellence.Read moreRead less
MODAL AND DIRECTIONAL CHARACTERISTICS OF SEASTATES AND THEIR IMPACT ON DYNAMICS OF MOORED OFFSHORE SYSTEMS. Under certain conditions a typical sea can becomes bimodal comprising of wind-driven seas and long period swells interacting from two directions. Using a nonlinear model, the occurrence and characteristics of bimodal and bi-directional seastates are quantified.
Low frequency oscillations of a moored offshore structure have profound design influence on the mooring system.

Under certain conditions a typical sea can becomes bimodal comprising of wind-driven seas and long period swells interacting from two directions. Using a nonlinear model, the occurrence and characteristics of bimodal and bi-directional seastates are quantified.
Low frequency oscillations of a moored offshore structure have profound design influence on the mooring system. A nonlinear response model for a floating vessel in bimodal and bi-directional seastates, will be developed using nonlinear dynamics techniques. The numerical models for the environment and the floating platform will be validated by experiments at the Ocean Basin in Canada.
The project adopts a holistic approach by considering the environment and the moored platform as a complex natural system. With excellent opportunities for technology transfer, the project also benefits from substantial in-kind contributions of the overseas PIs.

Oceanic Conditions within Extreme Tropical Cyclones. Australia's tropical and subtropical areas include major infrastructure projects such as the North West shelf oil and gas projects, major mining operations, export ports, natural environments such as the Great Barrier Reef and major tourism industries. All these industries are crucially impacted by extreme tropical cyclones. Despite the importance of these systems, our present understanding of tropical cyclones is incomplete. This project will ....Oceanic Conditions within Extreme Tropical Cyclones. Australia's tropical and subtropical areas include major infrastructure projects such as the North West shelf oil and gas projects, major mining operations, export ports, natural environments such as the Great Barrier Reef and major tourism industries. All these industries are crucially impacted by extreme tropical cyclones. Despite the importance of these systems, our present understanding of tropical cyclones is incomplete. This project will significantly enhance our ability to carry out accurate engineering design of critical offshore infrastructure, as well as marine forecasts in such environments. As such, the project will have major scientific, economic and social benefits for Australia.Read moreRead less
